What is claimed is: 
     
         1 . A display device comprising:
 a plurality of first prisms;   a plurality of second prisms; and   a display panel provided between the first prisms and the second prisms,   the display panel comprising:   a first substrate comprising a first transparent substrate and a pixel electrode,   a second substrate comprising a second transparent substrate and a common electrode opposing the pixel electrode, and   a liquid crystal layer provided between the first substrate and the second substrate and containing a polymer and liquid crystal molecules.   
     
     
         2 . The display device of  claim 1 , wherein
 each of the first prisms comprises a first apex opposing the first transparent substrate, and   each of the second prisms comprises a second apex opposing the second transparent substrate.   
     
     
         3 . The display device of  claim 2 , wherein
 the first apex has a first apical angle, and   the second apex has a second apical angle equivalent to the first apical angle.   
     
     
         4 . The display device of  claim 3 , wherein
 the first apical angle and the second apical angle are greater than 15° but less than 21°.   
     
     
         5 . The display device of  claim 2 , wherein
 each of the first prisms comprises a first surface substantially perpendicular to the first transparent substrate and a first inclined surface inclined with respect to the first transparent substrate, and the first surface and the first inclined surface form the first apex,   each of the second prisms comprises a second surface substantially perpendicular to the second transparent substrate and a second inclined surface inclined with respect to the second transparent substrate, and the second surface and the second inclined surface form the second apex, and   the first inclined surface is substantially parallel to the second inclined surface.   
     
     
         6 . The display device of  claim 1 , wherein
 the first prisms extend in a first direction and are arranged in a second direction intersecting the first direction, and   the second prisms extend in the first direction and are arranged in the second direction.   
     
     
         7 . The display device of  claim 1 , wherein
 the first prisms are arranged in a first direction and a second direction intersecting the first direction, and   the second prisms are arranged in the first direction and the second direction.   
     
     
         8 . The display device of  claim 1 , further comprising:
 a first cover member which covers the first prisms, and   a second cover member which covers the second prisms.   
     
     
         9 . The display device of  claim 1 , further comprising:
 a first transparent adhesive layer which adheres the first transparent substrate and the first prisms, and   a second transparent adhesive layer which adheres the second transparent substrate and the second prisms.   
     
     
         10 . The display device of  claim 1 , further comprising:
 a light-emitting element,   wherein the second transparent substrate comprises a side surface opposing the light-emitting element.   
     
     
         11 . The display device of  claim 1 , further comprising:
 a light-emitting element,   wherein   in the first prism, the first inclined surface is closer to the light-emitting element than from the first surface, and   in the second prism, the second surface is closer to the light-emitting element than from the second inclined surface.   
     
     
         12 . The display device of  claim 6 , wherein
 a space between each adjacent pair of first prisms and a space between each adjacent pair of second prisms are air layers.
